Inverse Property of Multiplication

Work Step by Step

RECALL:
The inverse property of multiplication states that for any nonzero real number $a$,
$a \cdot \frac{1}{a} = 1.$
In the given statement, $\frac{27}{5} \cdot \frac{5}{27}$ is equal to 1.
Thus, the given equation illustrates the Inverse Property of multiplication
